BEARING SUPPORT STRUCTURE AND GAS TURBINE

摘要

To provide a bearing support structure and a gas turbine that prevent damage of device induced by a rotor shaft when the rotor shaft is unbalanced, the bearing support structure and the gas turbine includes: a casing (7) formed in a cylindrical shape; a bearing unit (8) formed in a cylindrical shape and housed in the casing (7); a rotation shaft (5) rotatably supported by the bearing unit (8); and a reaction-force decreasing unit (13) that connects the casing and the bearing unit, and is configured to decrease a radial reaction force on the bearing unit side.
